Rocker B -C- #11 (API 42-383-33401) is a plugged well in Reagan County, plugged April 16, 2012, last operated by Discovery Natural Resources LLC.

The RRC has issued one drilling permit, issued March 8, 1985, permitted to 6,800 ft.

It was permitted by Kaneb Production Company and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Spraberry, Jo Mill, Dean, Wolfcamp.

Its lease has reported 111K barrels of oil and 570K mcf of gas since January 1993, last reporting in April 2015. The lease carries 11 wells, so these are lease totals, not this well alone.
